CYLINDER FOR HIDE-WORKING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 771,614, dated October4, 1904.

Application filed June 15, 1904:.

1'0 (l/M/ w/wm may concern:

Be it known that I, J AMES WVILLIAM DECK- ERT, leather-splitter, acitizen of the United States, residing in the town of Oakville, in thecounty of Halton and Province of Ontario, Canada, have invented certainnew and useful improvements in Cylinders for Hide-Vvorking Machinery, ofwhich the following is a specification.

My invention relates to improvements in cylinders for hide-workingmachinery; and the objects of my invention are, first, to provide asubstantially new cylinder for each of the different classes ofwork-such as unhairing, unfleshing, setting, and working out hides andstoning out hides withouthaving to provide an entire new cylinder forthese purposes; secondly, to permit of the speedy and easy renewal ofany of the blades or stories that may be worn out or damaged; thirdly,to provide a particular construction of blades for unhairing purposes,and, fourthly, to situate part of the blades so as to provide therighthand half of the cylinder with working-out and setting-out spiralsthat work the hide to the right and to situate the rest of the blades asto provide the left-hand half of said cylinder with the same spiralsthat work the hide out to the left; and it broadly consists,essentially, of a permanent metal foundation, preferably a shaft, aplurality of sections or rings removably held thereon, and a pluralityof blades or stones held in said sections or rings in such manner as toprovide a slight working-out spiral and a pronounced setting-out spiralaround the cylinder, as hereinafter more particularly explained.

My invention further consists in constructing the blades for unhairingpurposes out of rawhide, as hereinafter more particularly explained.

Figure 1 is an enlarged side elevation of part of my cylinder, showingsame provided with blades for unhairing purposes. Fig. 2

is a cross-section on the line a b, Fig. 1. Fig. 3 is a side elevationof oneof the working-out blades, and Fig. 4 is an end elevation of same.Fig. 5 is a side elevation of one of the setting-out blades; and Fig. 6,a cross-section on Serial No. 212,672. (No model.)

with blades or stones set at an angle or angles 4 which work the hideout to the right and the other half is provided with blades or stonesset at the same angle or angles which work the hide out to the left. Inmy preferred form of construction I use two kinds of blades for eachring or section and secure same therein at different angles. By securingthe work ing-out blades at an angle in each section or ring they make aslight working-out spiral round the cylinder, and by securing thesetting-out blades at an angle in each section or ring they make apronounced setting-out spiral round the cylinder. As will be understood,the Working-out and setting-out spirals in the right-hand half of thecylinder work the hide to the right and the same spirals in theleft-hand half work the hide to the left.

A is the permanent metal foundation, preferably a shaft, and same isprovided with ends a, designed to be held in any suitablejournal-bearing.

B represents the sections or rings designed to be slid onto the shaft A.I do not confine myself to any construction for securing the saidsections or rings on said shaft; but my preferred form of constructionfor this purpose consists of a key C, suitably secured to said shaft, asby screws 0. Each section or ring is provided with a central opening D,preferably round, so as to fit the shaft A, and a keyway E, in whichfits the key 0. By this construction it will be understood that the saidsections or rings may be easily slid on and off said cylinder and thatsame will necessarily rotate therewith. scribed, there are a number ofthese rings or sections held on said shaft, and each is pro- As beforedcvided with a plurality of blades or stones held at the required angletherein. I do not confine myself to any particular construction of bladeor stone, nor do I confine myself to any particular way of securing samein said sections or rings. Neither do I confine myself to necessarilyusing sets of blades or stones in said sections or rings, as it will beclearly understood that, for instance in stoning out hides, same kind ofstones may be used in the said rings and set at the same angle therein.

For the purpose of illustrating my invention I have shown two diiferentkinds of blades that I prefer to use in unhairing hides. The working-outblades F are secured alternately in the sections or rings and at aslight angle therein, so as to provide a slight working-out spiral roundthe cylinder, and the intermediate setting-out blades G are secured insaid sections or rings at an angle, so as to make a pronouncedsetting-out spiral round the cylinder. From this, and as beforementioned, it will be seen that by so placing the blades in saidsections the working-out and the setting-out spirals in the right-handhalf of the cylinder work the hide to the right and the same spirals inthe left-hand half work the hide to the left. My preferred form ofconstruction for securing the said blades in place is to provide thesections or rings with dovetailed grooves H and pack therein and aroundthe incased part of said blades any suitable material, such as cement orlead (Z, as shown. The endsf' of the working-out blades F preferablyabut the ends g of the settingout blades Gr. As will be clearly seenfrom the drawings, the ends f and r of said blades extend beyond thesides of the sections or rings, so that the said blades will overlappart of the path of movement of the blades in the adjacent sections orrings.

The working-out blades F are made of rawhide specially prepared andcompressed, and consist of a number of pieces It of rawhide placedtogether, as shown, and riveted by rivets As will be seen from Figs. 1,2, and 4-, the working edge of said blades F is shown square. Byconstructing the said blades from rawhide I obtain a lasting edge and adecided grip on the hide, pulling the hair more readily than any bladesheretofore designed for that purpose. These blades are also veryeffective on line hair and for taking out dirt, grease, and lime. Thesetting-out blades G are also specially prepared and compressed. Theyconsist of a central portion I, made of rawhide, over which is coveredthe outer portion J, also constructed of rawhide. By any suitable means,such as rivets j, the parts of the blade G are secured together. Theworking edges of the blades G- are rounded, as shown at O, and has avery excellent effect in setting-out the hide.

As will be seen from the drawings, the preferred staggered positions ofthe blades F and G in each half of the cylinder essentially make thesetting-out and working-out spirals have staggered sections.

I do not confine myself to the construction of the several parts nor tothe exact positions of the blades, as changes maybe made therein withoutdeparting from the spirit of my invention.
